  ABSTRACT:
  CDC reports incorrect CEC utilization for logical partitions

  COMMENTS:
  CDC code calculates CEC utilization percent by dividing the
  total utilization of all processors assigned to the LPAR by the
  total count of general purpose processors in the CEC. For LPARs
  with specialty processors assigned this will result in
  incorrect CEC utilization percent values.
  

Problem conclusion

• SOLUTION:
  The chosen solution is to update CDC to report LPAR CPU counts
  and utilization values solely based upon the shared general
  purpose processors. With this APAR applied, the CPUs column
  will be the number of shared general purpose CPUs assigned to
  the LPAR. The three utilization columns (LPAR utilization,
  Capped utilization percent, CEC utilization percent) will
  represent utilization of only the shared general purpose
  processor assigned to the LPAR.
  
  LPARs which have dedicated processors assigned or have only
  specialty processors assigned will be reported upon but their
  values (CPU count and utilization values) will be zeros.
